USACO tutoring with Mike Mossey

Your USACO journey begins with a great teacher


I’m Mike, a Caltech alum and former NASA employee who now tutors middle-school and high-school students in the U.S. Computing Olympiad (USACO).

My teaching philosophy

Over 9 years of teaching computer science (the last 2 dedicated to USACO) I have developed a teaching style that empowers students to have their own insights.

I encourage and praise my students for what they do right.

I maintain a focus on the big picture as well as the details.

I give my students chances to have their own insights and tools to help them become better teachers to themselves.

If you would like to get started, I can give your student a free 30-minute evaluation to find out where they’re at and how lessons can  benefit them. Feel free to contact me to schedule it.
